I MORTAR-MIXER.

SPECIFICATION forming part of Letters Patent No. 295,196, dated March 18, 1884. Application filed January 29, 1884. (No model.)

To all whom it may concern Belt known that I, WrLnnLrnr Pnoonnow, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain newand useful Improvements in Mortar-Mixers, and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to mortanmixing machines, and will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation of my machine connected with a horsepower motor and ready for work. Fig. 2 isa top view of the same. Fig. 3 shows a longitudinal vertical section of part of the machine, and Fig. 4 is an enlarged top view of one of the mixingknives.

A is themixing-box,wl1icl1 may be mounted on its own wheels c c, (shownin dotted lines) or on any form of detachable supportsA A. A door, B, fitted with asuitable latch, a, is hinged in the center of either one of the box sidesjor convenience in filling in the materials as well as emptying the mortar. the upper edge of the box sides are the standards 81 Z) b b, on top of which are laid the rails c e,firnily bolted thereon. The end standards, I) b, have extensions if 6*, securely fastened therewith, and to the upper end of which are bolted the upperv rails, c a, and between these rails e c and the lower one, o c, are mounted two pair of flanged wheels, 0 G and G G, both of said wheels being made of a diameter to run loosely between said rails c and c, this latter being intended as a guardrail for the wheels. Each pair of wheels runs on the journaled ends of a square axle, D D, and the journals of the axle D are extended out to be connected by pit-men E E to the crank of the driving-wheel F of the motor used, these pitmen E E and their attachment to the wheel being obviously proportioned to the length of the box A. The square axles D and D carry the mixing-knives e e e a e e o 8'. These knives consist of the body e and the stem e, projecting upward from the center of said body, edges of which are given a suitable point to out either way through the material to be mixed. The stem 6* of the knives is connected to the square axles D and D by means of a clamp, (I, firmly bolted thereon,

Bolted in and a nut, d, working in the upper threaded end of said stein c and against the collar d of the same, serves to tighten the knife in said clamp d. The knives are attached so as to alternate together on both sides of the axles, and their lower end works close to the bottom of the box A. The axles D and D are main tained at a certain distance from each other and are connected by means of the bars or rods f f, one end of which hinges in any suitable manner in I), and its opposite end is bent down to hook in the 'eye of a staple, g, of the axle D. This connection allows of bringing the two axles together at the end of the box A nearest to the motor, to facilitate the filling in of the materials and the emptying of the'mortar, the bar and the knives on axle D, shown in dotted lines in Fig. 3, illustrating their position in relation to the knives or" axle D without regard to the box itself.

The operation of my machine may be readily understood from the above description. The mixing of the mortar is speedily and etficiently produced by the back-and-forth 1110- tion given to the knives in the whole length of the mixing-box. The double pointed knives are constantly brought in contactwith different parts of the mass, every particle of which is thrown to one side or the other of the knives until perfecthomogeneity has been attained. This is obtained with my machine very promptly and at much less expense, as well as with much greater thoroughness than by ordinary hand-work.

I have represented my machine connected with a horse-power machine, as this motor is the one apparently the best adapted to the driving of a portable mortar-mixing machine, but obviously any other motor may be used,if desired; and it must also be understood that I do not restrict myself to the particular form of box or the manner of attachment of the knives shown and described, as these may be varied considerably without departing from the spirit of my invention.

Having thus described my lllVGlllllOlhWllZtli I claim as new, and desire to secure by Letters Patent, is-

In a mortar mixing machine, the box A, having the hinged door 13, supports 1) 2) b b for the rails c c, and extensions Z) Z) forthe guardhave hereunto set my hand at Milwaukee, in rails c c, in combination with the wheels 0' the county of Milwaukeeand State of Wiscon- 1o 0 and O O,aX1esD and D,bearing the knives sin in the presence of two witnesses. e e e e e 6 bars or rods f f and pitmen E T 5 E of the di iving mechanism,substantially as VILHELEM PROOHL shown and described, and for the purpose set Witnesses:
